Procedure
A stirred mixture of 2.8 g. (0.01 mole) of 4-chloro-1,7-dimethyl-1,2-dihydro-2-oxo-1,8-naphthyridine-3-carboxylic acid ethyl ester, 0.7 g. (0.01 mole) of pyrrolidine and 1.06 g. (0.01 mole) of sodium carbonate in 30 ml. of ethanol was heated under reflux for 5 hours. The mixture was filtered and the filtrate was cooled in ice. The precipitate which formed was collected and was recrystallized from heptane to give 1.7 g. of product, m.p. 108°-111° C.
